I don't understand what you are asking.

Are you asking "what is the difference in $\\1)~\left( {\forall x} \right)\left( {\exists y} \right)\left[ {M(y,x)} \right]\\2)~\left( {\exists y} \right)\left( {\forall x} \right)\left[ {M(y,x)} \right]~?$

If you are, think of $M(a,b)$ means "a is the mother of b".

1) Says Everyone has a mother.

2) Says someone is the mother of everyone.

If that is no what you are asking, type out (DO NOT USE AN ATTACHMENT) the question.

Explain in detail you problem.
